Convection and Radiation
This method of heat transfer occurs only in liquids and gasses
What is convection?
During a change of state, temperature stays the same, which means that particles have _________ speed
What is unchanging?
On a graph of temperature over time, this flat spot is seen during changes of state
What is a plateau?
What are metals?
A bowl of soup is at 90 degrees in a 20 degree room. The soup begins to cool. What temperature does it stop at?
What is 20 degrees?
This method of heat transfer occurs without the movement of any matter or particles
What is radiation?
As a solid heats up, what happens to its particles?
This type of variable is commonly found on the x-axis of a graph
What is manipulated?

1. Air popper
2. Stovetop
3. Microwave
What is stovetop?
Which of the following methods of cooking popcorn would use convection?
1. Air popper
2. Stovetop
3. Microwave
What is an air popper?
Ocean water becomes warmer during the summer months because of ________ currents
What is convection?
Which of the following would have the most space between their particles?
Solid wood at 20 degrees C
Liquid mercury at -20 degrees C
Solid plastic at 50 degrees C
What is mercury?
This type of variable is often found on the y-axis of a graph
What is responding?
Wearing oven mitts when taking something hot out of the oven is a safe way to avoid burns by conduction. This is because oven mitts are
What are insulators?
This is the name of the pig in our class
What is Henry?
Which of the following methods of cooking popcorn would use radiation?
1. Air popper
2. Stovetop
3. Microwave
What is microwave?
A wooden spoon and a metal spoon are resting on a pot of soup on the stove. Which spoon would heat up faster and why?
What is metal? What is a conductor?
This graph feature helps to identify different lines on a line graph
What is a legend?
Why are metals typically good conductors and wood usually is not? (answer does not have to be a question)
Particles in metals are rigid and packed tighter together. Particles in wood have more space between them and less heat is passed between the particles
The average speed of particles in a substance
What is temperature?
During the summer, the bark on the logs in my campfire would pop up, float a little higher, and then fall to the side. Why does this happen? (this answer does not have to be in the form of a question)
Convection currents rising from the campfire - warm air carries the pieces of bark upwards, then as they cool, they fall back down to the side
What is reorganizing/rearranging?
Not including these in your axis labels will cause you to lose at least one full mark
What is a unit of measurement?
This person normally stands in front of an orchestra and directs the music
What is a conductor?
The total energy of a substance
What is thermal energy?
